## a b s t r a c t This work deals with a singularly perturbed initial value problem for a quasi-linear secondorder delay differential equation. An exponentially fitted difference scheme is constructed, in an equidistant mesh, which gives first-order uniform convergence in the discrete maximum nor
## Abstract We consider the numerical approximation of singularly perturbed reaction‐diffusion problems over two‐dimensional domains with smooth boundary. Using the __h__ version of the finite element method over appropriately designed __piecewise uniform__ (Shishkin) meshes, we are able to __unifo
